Psychological thriller on the high seas "Caught Inside" (2010) is an Australian psychological thriller about a group of surfers who sail to a remote island paradise for vacation. A couple of women join the expedition at the last moment and a series of events turns the holiday into a torturous adventure. What I liked about this film, aside from the professional fimmaking and paradisical locations (Maldives), was the realism of the story and characters. The film skirts the borders of the slasher genre and I'm sure it was tempting for the writers to have someone morph into Jason Voorhees, but they wisely resisted. SPOILER ALERT Someone complained about how unbelievable it was at one point when a group of four or five from the expedition "cowardly" put up with the psycho's tormenting antics when he doesn't even have a weapon. But this is where the film shines as a PSYCHOLOGICAL thriller. Bull, the psycho, had gained the upper hand by this point in the story. The others are literally afraid of him and fearing for their lives. They're also in shock since this was supposed to be a paradise surfing vacation. The blond guy with short hair tried to scrap with Bull a couple of times and was easily humbled, not to mention beat up. It's a mental thing. Bull is the king of the mountain at this juncture -- "king" by brute force and arrogance alone. One of the girls, Sam, is anticipating getting raped and who knows what else. The teen dude doesn't know what to do, since he was Bull's little buddy, but now he sees what a total psycho he is. So they're all afraid and considering their options. No doubt they're thinking of ganging up on him, but they simply don't have it in them at this moment, so they endure his tormenting antics. They're also waiting for the right opportunity when their chances of success are best. I didn't find this unbelievable at all; in fact, I found it very realistic. END SPOILER If you like films like the excellent "Dead Calm" (1989), be sure to check out "Caught Inside." It's not as good, but it comes respectfully close. By the way, the Australian accents are thick so I recommend using the subtitles. The film runs 93 minutes. GRADE: B+
